First of all the selection of directory favourites works find. When you type the first unique letter (a short cut) from the favourites list TC goes to that directory. When you have two directories starting with the same letter like Downloads and Documents it does not work. When you change the name in e.g. D&ocuments, the letter o is the short cut and should be displayed with an underscore under the o.
There are 3 ways to display that favourites. Only CTRL-D shows correctly the underscored letter which is the short cut. But when you use the * or double click on the directory bar to display the directory favourites they are shown without the underscore (but the selection still works). No immediate attention is required but it should be nice if it is put right in a next release.

When I press the (left) Alt key and then all of the three ways use, the menu does not appear. And the other way around the menu disappears when I press the Alt key afterwards. I surprises me that the 3 ways to show the directory menu don't use the same procedure to show the results.
